not me (yet) but my wife is...
She's studying for both certification and a degree in information systems. Right now she's mid-way thru an online Java programming course, and things seem to be progressing apace (she's doing very well, in any case, and will likely soon want my job!)
Prior to the Java class, she completed an English course via the Net, and altho she did fine, it was much more difficult due to the poor organization and operation of the course website. If we took a lesson out of that, it's to give a course time to mature in its online incarnation before enrolling. IMO, even those who are outstanding at classroom instructional design *may* need help creating effective online education.
